								<p><span><strong>Summary:</strong> This dataset, a modified and updated version of POLITY II: 
 POLITICAL STRUCTURES AND REGIME CHANGE, 1800-1986 (ICPSR 9263),
 focuses on indicators of political authority and regime type 
 for 177 members of the international system. Variables include two 
 indicators of regime type (autocracy and democracy) and eight 
 indicators of political authority (regulation of executive recruitment, 
 competitiveness of executive recruitment, openness of executive 
 recruitment, monocratism, constraints on the chief executive, 
 regulation of political participation, competitiveness of political 
participation, and centralization of state authority).</span></p>
